Tiber Island in the context of "Tiber"

The Tiber (/ˈtaɪbər/ TY-bər; Italian: Tevere [ˈteːvere]; Latin: Tiberis) is the third-longest river in Italy and the longest in Central Italy, rising in the Apennine Mountains in Emilia-Romagna and flowing 406 km (252 mi) through Tuscany, Umbria, and Lazio, where it is joined by the River Aniene, to the Tyrrhenian Sea, between Ostia and Fiumicino. It drains a basin estimated at 17,375 km (6,709 sq mi). The river has achieved lasting fame as the main watercourse of the city of Rome, which was founded on its eastern banks.

The river rises at Mount Fumaiolo in Central Italy and flows in a generally southerly direction past Perugia and Rome to meet the sea at Ostia. The Tiber has advanced significantly at its mouth, by about 3 km (2 mi), since Roman times, leaving the ancient port of Ostia Antica 6 kilometres (4 miles) inland. However, it does not form a proportional delta, owing to a strong north-flowing sea current close to the shore, due to the steep shelving of the coast, and to slow tectonic subsidence.

Ospedale Isola Tiberina – Gemelli Isola is a hospital in Rome, established in 1585 and located on the Tiber Island on the site of an ancient temple dedicated to Aesculapius. Formerly operated by the Brothers Hospitallers of Saint John of God as San Giovanni Calibita Fatebenefratelli Hospital, it adopted its current name after the company Gemelli Isola – Società Benefit S.p.A. acquired it on 1 September 2022.

Throughout its history, the hospital has served as a sanctuary for marginalized and persecuted groups. During the Holocaust, it sheltered Jews from Nazi persecution by admitting them as patients and diagnosing them with a fictitious disease known as "Syndrome K."

The Basilica of St. Bartholomew on the Island (Italian: Basilica di San Bartolomeo all'Isola, Latin: Basilica S. Bartholomaei in Insula) is a titular minor basilica, located in Rome, Italy. It was founded in 998 by Otto III, Holy Roman Emperor and contains the putative relics of St. Bartholomew the Apostle. It is located on Tiber Island, on the site of the former temple of Aesculapius, which had cleansed the island of its former ill-repute among the Romans and established its reputation as a hospital, continued under Christian auspices today.

Its cardinal priest has been Cardinal Blase Cupich since 19 November 2016.
